ADAM REIN, OF HAMILTON, OHIO.

BEEFSTEAK-TENDERER.

SPECIFICATION forming part of Letters Patent No. 311,527, dated February 3, 1885.

Application filed May 2, 1884. (No model.)

To all whom it may concern:

Be it known that I, ADAM REIN, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvementsin Beefsteak-Ienderers, of which the following is a specification.

This invention pertains to that class of beefsteak-tendering devices which effect their purpose by subjecting beefsteak to the action of dentigerous surfaces.

The invention will be readily understood from the following description, taken in (ma nection with the accompanying, drawings, in which Figure 1 is a side elevation of a machine embodying my improvements; Fig. 2, a perspectiveview illustrating the character of the surfaces which act upon the beefsteak, and Fig. 3 a vertical section of portions of the machine upon the line P of Fig. 1.

In the drawings, A represents the baseboard of the machine; B, a die-plate secured thereto and having its upper surface provided with pyramidical teeth, about as indicated in Fig. 2; G, a movable platen operating above the plate B in an obvious manner, and provided upon its under surface with similar teeth arranged to enter between the teeth of the die-plate; D, a rod or plunger secured to the platen E, a fixed guide through which the plunger slides; F, a standard. secured to the base-piece and serving to support the guide E, and also afulcrum-pivot for the operating-lever; G, the operating-lever of the device; H, a counterbalance-weight upon the rear end of the lever G, adapted to over-balance the plate, &c., and to hold the same open or in its upward position; I, adislc' journaled in the lever over the plunger and bearing with its periphery upon the top of the plunger; J, upwardly-projecting jaws at the top of the plunger, straddling the lower portion of the disk I, as clearly shown in Fig. 3; K, pins projecting inward from the jaws of the plunger and engaging upon the inside of the flange of the disk; L, side flanges at the periphery of the disk; M, the pyramidical teeth arming the faces of the die and platen, and Nthe mortise in the lever in which is journaled the disk.

the cells are broken up, the juice set free, and the beefsteak rendered more tender andpalatable after being cooked. When the lever moves upward the plunger is pulled up by means of the pins K engaging over the flange of the disk, slight rotation of the disk serving to endow the disk with all the properties of an articulating connecting-rod free from rubbing friction, except at its axle. lVhen the lever is depressed and considerable re sistance met with in the performance of the Work of the'machine the power is transmitted from the lever to the plunger through the periphery of the disk engaging the top of the plunger, as indicated in Fig. 3, the pins K serving no function during the downstroke, the slight rotation of the disk again furnishing the elements of the parallel motion. The bases ofthe teeth of the plates do notjoin each other; but, on the contrary, the plates exhibit considerable area of plain surface between the teeth. It is essential to the success of the apparatus that the plates should be so constructed.

I have found in practice that if the teeth are packed so closely together that the teeth of the two plates simply intermernber with each other the effect upon the meat is about the same as if the meat were pressed between two plain surfaces. By setting the teeth so that their bases do not join, thus leaving plain surfaces between the teeth, I am enabled to accomplish reasonably fair results with one dentigerous surface acting against one plain surface, results far superior to anything Which can be accomplished by even two surfaces of closely-packed teeth.

I claim as my invention- The combination of the die-plate B, platen 0, having plunger D, provided with inwardly-projecting pins K, the standard F, supporting a lever-pivot and a plunger-guide, the lever G, having a mortise provided with a journal-pin, and the disk I, journaled within said mortise and provided with side flanges, L, engaging the top of said plunger and under the pins at its top, substantially as and for the purpose specified.

ADAM REIN.
